    Solar Power NZ: A case study

     Last year Defkalion publicly demonstrated what they thought was evidence of overunity with their LENR device. What did not get publicized was when the experiment was run again with the LENR device switched of, the same results were observed.

    The reoccurring problem I see when it comes to free energy claims are methodology, inadequate instrumentation or really bad interpretation of data. Sometimes they are deliberate to mislead, but in the majority of cases is just a lack of qualifications, experience or ignorance.

    I along with many others, have been critical on the measurement techniques and equipment used by Rossi, Defkalion  and a few others when making LENR performance claims. I am often asked about my own opinion which has not changed after many years. LENR is not understood, it is an anomaly or an event that can not be reliably repeated. It is worthy of further research (and a lot of credible research continues) but I feel it will be years, if ever, that they are able to engineer it into a useful continuous process. I am a supporter of further research. I am also very critical of fund raising efforts undertaken by some based on poor testing and dubious results.

    Mats Lewan was there at the Defkalion demonstration last year. He is an internationally recognized and respected  journalist when it comes to all things to do with LENR. He is the author of a book ‘An Impossible Invention’ which I highly recommend. The following excerpts were taken from his blog earlier this year and is an excellent example of the politics of measurements. Please go to the following link for the full version as it is a great read.


    Measurement Error

    The measurement setup that was used by Defkalion Green Technologies (DGT) on July 23, 2013, in order to show in live streaming that the Hyperion reactor was producing excess heat, does not measure the heat output correctly, and the error is so large that the reactor might not have worked at all.

    This is the conclusion of a report  by Luca Gamberale, former CTO of the Italian company Mose srl that at that time was part of the joint venture Defkalion Europe, owned together with DGT.

    Link to report:

    The report is based on experiments, performed mainly after the live streaming, using the same setup but without the reactor being active. Yet, the experiments showed that it was possible to obtain a measured thermal power of up to about 17 kW, while the input electric power was about 2.5 kW.



    Recommendations not followed

    Gamberale describes in the report that before the demo, Mose had proposed a series of improvements to the measurement setup in order to make it more reliable but that DGT did not allow these changes. He notes that the lack of cooperation made it necessary to carry out independent verification tests.

    The tests focused on a possible malfunction of the digital flow meter used to measure water flow in the setup. It was shown that by decreasing the input water flow to almost zero, the flow meter started to make fast movements back and forth, and since the direction of the flow was not registered by the flow meter, these fast movements resulted in a reading corresponding to a relatively high flow, although the flow was almost zero.

    Since the calculation of thermal heat was based on how much water was heated by the reactor, this measurement error resulted in a large calculated thermal heat output, while the actual thermal heat was much lower.

    The explanation is thoroughly discussed in the report. Most important, however, is the fact that Gamberale with the experiment has proved that the setup could produce readings of large amounts of excess heat, without the reactor running, and that any result from the setup showing excess heat therefore is unreliable.


    Gamberale doesn’t accuse Defkalion openly for fraud, but he makes it clear that the Milan demo presented no evidence that the technology is working.

    Gamberale has a PhD in theoretical high energy physics from the University of Milan, and at the Milan based Pirelli Labs he has further developed the theoretical work in coherent electrodynamics by his countryman, late Dr. Giuliano Preparata. Among his experimental work he has been assessing the technology of Black Light Power. He has also made studies on electrochemical loading of palladium wires.

    Defkalion’s Future


    Mats Lewan

    Defkalion’s president Alexander Xanthoulis  still claims, however,  that the development of the new reactor is on track and that according to the plans it will be certified with regard to safety and security by a Canadian certifying body corresponding to US Underwriters’ Laboratory within the next months. After that, Defkalion could start licensing the technology to partners. National licenses were previously offered at EUR 40.5 million, and though Xanthoulis told me that five contracts have been signed he also said that no money had yet been transferred.

    But Defkalion will now have to present solid evidence to convince anyone that its technology is valid, and also let those people make changes to the test protocol and to the measurement set-up, if it’s necessary in order to eliminate uncertainties.

    Gamberale told me that the findings he describes in the report could bring damage to serious research activities within LENR, but he also told me that he personally still believes that LENR is an important scientific and technological area and that he is getting involved in two other projects in this domain.
